This contribution aimed to investigate the poorly studied bird fauna of Bousaâda oasis. The direct observation method was used for bird counts, adopted only during the breeding period. A total of 53 species of birds from 29 families and 16 orders were assessed in the different habitats of the Oasis (palm, fruit trees and, cultivated crops). The Passeriformes order was the most abundant represented by 35 species and 16 families. The relative abundance and species richness were recorded during our study period over different seasons and thought that whole surveyed stations represent all the oasis habitats. The Boussaâda oasis holds 18 resident-breeders which is a transit zone for a number of migratory birds i-e 14 and 10 species for summer and winter migrants respectively) and11 occasional visitor ones. These results confirmed the positive effects of stations and seasons on the richness and abundance of birds of Bousaâda oasis.

However, the ecological Biodiversity studies attracted the characteristics of oases in Algeria varied world’s attention to find its impacts on between regions following their humans and provide parallel ecosystem geographic location. Although, the services (Harrington et al., 2010). During ecosystems of arid and desert regions has the last century, reduction in biological very peculiar biodiversity related to locale diversity has directly affected the human biotope and climate (McGinley, 2007) activities (Heywood and Watson, 1995). particularly birds (Roshier et al., 2001; The oasis is considered as a fragile Mwaura, 2010; Chenchouni, 2012). ecosystem of the arid climate.

Some studies were (Botes and Zaid, 2002). available on birds of oases in Algeria Oases help study survey (Boukhemza, 1990; Chenchouni, 2012; biodiversity and their ecological Bensaci et al., 2013) but these were limited characteristics because of their key to few regions and were occasionally habitats (Chenchouni, 2012). According to observed. 11 Chiheb et al. (2021). Spatio-Temporal Variation of Bird Community in Sahara.

Overall, these stations located in four (4) studied regions: Zakat El-Kib (ZEK), Loulaj (LLJ), JnanLebtom 1 (JB1) and, JnanLebtom 2 (JB2) (Table 1). These regions have different habitat characteristics. Depending on their location, the surveyed stations are the subject of varied urban pressure and human disturbance. Phenological types used were (1) resident breeder (RB) species present all year with breeding proof; (2) winter visitor (WV) species observed exclusively during the rainy Figure 1: Study area location. season; (3) summer visitor (SV) migratory species in summer; (4) occasional visitor Bousâada oasis is the first one (OV) species that observed in the study encountered while heading from the region at least once (Isenmann and Moali, coastline to the Sahara Desert (Boutabba, 2000). 2013) Oasis is crossed by Oued Bousâada, During the study period the total flowing at the foot of a huge cliff used for numbers of species counted at each station irrigation.
